I am using a Cat 4510R, with supV, and want to use linecard WS-X4148-RJ21 in slot 10.
I receive an error: C4K_CHASSIS-3-LINECARDNOTVALIDINSLOT, but I cant find anything on cisco.com that slot 10 is different from the other slots. Only slot 1 and 2 are for supervisor, the other slots should support all the cards.
Does anyone has had the same problem?
Note that there is a small white vertical bar on the left of the slot, like there are 2 blue bars on slot 1 and 2.
